Improvement in thill-couplings



UNITED STATES PATENMFM AMANDUS WOEBER, OF DAVENPORT, lOl/VA.

Specilication forming part of Letters Patent No. l 52,447, dated J une23, 1874; application filed December 12, 1873.

' which- Figure l is a front elevation. Fig. 2 is a vertical sectiontaken on line s s of Fig. 1. Fig. 3 is a transverse section of thesockets, pivot, and king-bolt, as indicated by line cc cc of Fig. 1.

My invention relates to an improved carriage-couplingand king-bolt; andconsists otl a cliphaving a socket to receive a pivotal socket on thehead-block plate, and a kingbolt, which extends through the sockets andthe head-block and springs'. The clip is made with broad tlanges,forming bearings to iit and rest 011 the wood part of the axle, and thesocket and pivot are tapered, so as to be slightly larger at the top,and the pivotal socket extends entirely through the clipsocket andslightly below a recess formed at the bottom ofthe socket to receive thetlanged head ot' the king-bolt, so that the lower end of the pivot formsthe bearin g ot' the head ot' the king-bolt, which is held in place by anut on the top of the holt.

The object of the invention is to prevent the liability existinginordinary couplings of twisting oit' the kin g-bolt.

A represents the clip, made with anges b to fit over the axle, andforming bearings sufficiently large to prevent wearing or sinking intothe wood part of the axle B. A' is the clip-socket, provided with arecess, c, at the bottom to receive the flanged head of the king-bolt,and the socket is made to taper slightly, so that its diameter isslightly larger at the top than at the bottom. B' is a pivotal socketvon the head-block plate C, which pivot is made slightly tapering to litthe socket A', and extends entirely through and sufriciently below thesocket to form the bearing of the head of theking-bolt, as shown in Fig.

2 ot' the drawings. D is the king-bolt, having a flanged head, d, andthe lower part of the bolt is square to fit the square part of itssocket formed on the lowerA end of the pivotal socket B', as shown inFig. 3, so that the bolt may not turn in but -with its socket. The boltis held in place by a nut, c, on the upper end, by which the head d istightly drawn against the lower end ot the pivot B', and the springs andhead-block are firmly held on the coupling.

Instead of making the lower part ot' the bolt and pivotal socket square,the head of the bolt may be provided with a lip or lug to lit in arecess in the lower part of the pivot B', to prevent the bolt fromturning.

AThe king-bolt is introduced at the bottom of the clip-socket before itis attached to the axle, and being arranged not to turn on its socket,and the head ot' the 'bolthaving its bearings on the end of the pivot,as described, the coupling may be tightened by screwing down the nut cto any required extent without att'ectii'ig in the least the free motionof the coupling, and without any liability, in use, of twisting oil thebolt.

I am aware that, there are clips provided with ianges and-with sockets;but none of them are constructed to receivea pivotal socket throughwhich the kin g-bolt passes, as herein described.

What I claim as new, and desire to secure by Letters Patent, incarriage-couplin gs, is-

1. A clip-socket, A', in combination with a pivotal socket, B', andVking-boltV D, substantial] y as and for the purposes described.

2. The pivotal socket B', in combination with the bed-plate C,clip-socket A', and kingbolt D, substantially as described.

3. The clip A, having anged bearings b, and clip-sockets A', havingrecess c, in combination with pivotal sockets B', plate C, and king-boltD, substantially as and for the purposes described.

In testimony that I claim the foregoing I have hereunto set my hand this22d day ot' November, 1873.
